> would have thought it would be fine on the normal puppy food and I would only use food for large breeds if the pup was eating so fast it was in danger of choking itself. What are you feeding?
Nova, food specifically for large breeds has nothing to do with the size of kibble it is specifically formulated to maintain a slower growth rate, since large breeds sometimes to not fully mature skeletal wise until around 3 years old... a fast growth rate on large and giant breeds can be quite damaging to joints and bone density. Labradors are classed as a large breed. A Spring x Lab is prone to the same problems of HD and OCD.
to the OP... Labradors are notorious for scoffing food but Springers are not (at least the two I had weren't) and I pretty much left food down all day for them to eat as and when....I have also noticed that when my pups go to new homes, owners have told me the same thing as yourself, and I have occassionally noticed lack of interest in food in the pup I keep once littermates have gone.... They simply don't have a race anymore, so any food does not have to be eaten immediately (yes, I know I am placing human thoughts on an animal lol.) but I have noticed it on a few occassions when keeping a single pup... however, when I keep littermates,, we still have a race to who can eat more and fastest..
If your pup is a decent weight, I would not worry too much.
